FANCM promotes PARP inhibitor resistance by minimizing ssDNA gap formation and counteracting resection inhibition

Cell Reports
Summary: Poly(ADP-ribose) polymerase inhibitors (PARPis) exhibit remarkable anticancer activity in tumors with homologous recombination (HR) gene mutations. However, the role of other DNA repair proteins in PARPi-induced lethality remains elusive.

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Chimerization of antibodies by isolation of rearranged genomic variable regions by the polymerase chain reaction [PDF]

, 1991
We describe a new method for amplification, by polymerase chain reaction (PCR), of rearranged segments encoding the variable part of light and heavy chains of an antibody (Ab) from the chromosomal DNA of hybridoma cells for the chimerization ofAbs.

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

Molecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Navigating directed evolution efficiently: optimizing selection conditions and selection output analysis

Frontiers in Molecular Biosciences
Directed evolution is a powerful tool that can bypass gaps in our understanding of the sequence-function relationship of proteins and still isolate variants with desired activities, properties, and substrate specificities.

Low Cost DNA Molecular Weight Marker: Primer-Directed Synthesis from pGEM-T Easy Vector

Walailak Journal of Science and Technology, 2011
A low cost DNA molecular weight marker was produced by a marker primer-directed synthetic method using pGEM-T Easy vector as the DNA template. Seven primers were used to amplify eight different DNA fragments, which were 150, 300, 375, 500, 700, 1,000, 1 ...

Polyamines stimulate DNA-directed DNA synthesis catalyzed by mammalian type C retroviral DNA polymerases.

Journal of Biological Chemistry, 1981
In the presence of optimal concentrations of Mg2+, rates of activated (gapped) DNA-directed DNA synthesis by purified mammalian type C retroviral DNA polymerases are stimulated greater than 10-fold by the polyamines spermine and spermidine.

Stimulator of interferon genes agonist augmented antitumor immunity of osimertinib in Egfr‐mutated lung cancer

Molecular Oncology, EarlyView.
Combining osimertinib with the STING agonist ADU‐S100 activates innate and adaptive immunity to overcome the non‐inflamed microenvironment of Egfr‐mutant lung cancer. This combination increases NK and CD8+ T‐cell infiltration, associated with activation of the STING‐IRF3 pathway and local immunogenic cell death.

A mutant Pfu DNA polymerase designed for advanced uracil-excision DNA engineering

BMC Biotechnology, 2010
Background The combined use of restriction enzymes with PCR has revolutionized molecular cloning, but is inherently restricted by the content of the manipulated DNA sequences.
